3-methoxy-4-hydroxy-5-all-trans-hexaprenylbenzoate, also known as 3-hexaprenyl-4-hydroxy-5-methoxybenzoate anion, is a member of the class of compounds known as sesterterpenoids. Sesterterpenoids are terpenes composed of five consecutive isoprene units. 3-methoxy-4-hydroxy-5-all-trans-hexaprenylbenzoate is practically insoluble (in water) and a weakly acidic compound (based on its pKa). 3-methoxy-4-hydroxy-5-all-trans-hexaprenylbenzoate can be found in a number of food items such as borage, apricot, red rice, and buffalo currant, which makes 3-methoxy-4-hydroxy-5-all-trans-hexaprenylbenzoate a potential biomarker for the consumption of these food products.
